Title: Production of irregular shape metallic articles
Inventor: MORITOKI MASATO
IPC: B22F3/15
Filed: 1980-03-05
Abstract: PURPOSE: To produce irregular shape articles easily from metal materials which are not in the form of powder by combining and disposing solid blank materials in a manner as to coincide approximately with the surface shape of dies, loading and sealing these in a capsule and subjecting the capsule to hot hydrostatic pressing.  
     CONSTITUTION: Solid metal blank materials 1aW1g are suitably disposed approximately along the surface shape of a die 3, and are loaded into a capsule 2 for hot hydrostatic pressing. Air is vented from a deaerating pipe 4 provided to the upper cap 2a of the capsule 2, and the pipe 4 is sealed hermetically by forge-welding. Thence, the capsule 2 is charged into a hot hydrostatic pressing furnace, where it is treated for about one hour in, for example, an Ar gas atmosphere of about 1,150°C and about 1,000 atmospheric pressure. Thereby, the materials 1aW1g are plastically deformed along the shape of the die 3 and the respective blank materials are mutually diffusibly bonded to develop firm bond, thus the molding and bonding is accomplished simultaneously. A material which does not cause plastic deformation in hot hydrostatic pressing is selected for the die material.

IPC: B60W10/10
Filed: 1984-02-17
Abstract: PURPOSE:To facilitate the operation of speed change by setting a semi-connection stop position to the connection side rather than the starting side in the acceleration of a vehicle. CONSTITUTION:Outputs of an accelerator pedalling amount detector 10, an engine rotational frequency detector 50, a position detector 54, a vehicle speed detector 58 and a shift position detector 60 is supplied to the input of an engine controlling circuit 12.

IPC: C07C49/743
Filed: 1979-03-12
Abstract: NEW MATERIAL:A bicyclooctane derivative of formula I (Y and Y' are H or hydroxyl-protecting groups).  
     EXAMPLE: 2β-( 3'-Trityloxy-trans-1'-propenyl )-3α-hydroxy-bicyclo( 3,3,0 )octan-7- one.  
     USE: An intermediate for synthesis of prostaglandin analogs having a powerful blood platelet aggregation inhibitory effect.

Title: Wedge bonding tool
Inventor: SHIMIZU JUICHI
IPC: H01L21/60
Filed: 1999-02-05
Abstract: PROBLEM TO BE SOLVED: To provide a tool adapted to wedge bonding at narrow pitches by forming a groove in the flat bottom surface of the tool so as to extend in parallel with a wire and setting the width and depth of the groove within a predetermined range of percentages with respect to the diameter of the wire. SOLUTION: In a wedge bonding tool 2, a groove 1 is formed in the flat bottom surface of the tool so as to extend in parallel with a wire 3. The width and depth of the groove 1 are set to 80-120% and 20-60% of the diameter of the wire 3, respectively. By using such a bonding tool 2, the wire collapsed width can be kept within about 1.2-1.3 times the diameter of the wire 3. The reason why the width and depth of the groove 1 is limited is because when the width and depth of the groove 1 exceed 120% and 60% of the diameter of the wire 3, respectively, the bondability of the wire 3 cannot be ensured, and when the width and depth of the groove 1 are smaller than 80% and 20% of the diameter of the wire 3, respectively, the wire collapsed width cannot be kept under a predetermined value.

Abstract: PURPOSE:To take paper sheets out in a simple manner by installing a rotatable lever in the lower part of a box body of a sorter, and projecting the paper sheets partitively housed in plural numbers of sorter bins from each bin with the lever slid. CONSTITUTION:A lever 16 is rotatably attached to the lower end of a box body 11a of a sorter 11 with sorter bins 14a-14n housing sorted sheet paper. A slit, where the lever 16 is insertable, is formed on a surface being opposed to the lever 16 of these sorter bins 14a-14n. In addition, a part of these sorter bins 14a-14n is bent so as to prevent the sheet paper from getting into the slit and thereby each of ramps 19a-19n for entering prevention is formed in the sorter bins 14a-14n. The lever 16 is always energized to be situated at the outside of the slit. At time of takeout of the sheet paper, the lever 16 is thrust in the slit by hand, and the housed sheet paper is partially extruded by these bins 14a-14n. Consequently the takeout comes easy.

Abstract: PURPOSE:To reduce memory capacity used for the phase deciding circuit of a reception part at the MODEM while adopting the same modulating/ demodulating system for both of a main channel and a secondary channel concerning the MODEM which is suitable inside a network. CONSTITUTION:A demodulating means 4a is provided with a timing phase deciding means 7a for inputting a demodulated vector signal sampled to a digital value and for deciding which part of plural divided judging planes where the phase of this input signal exists, and the timing phase deciding means 7a defines a rotary vector rotating the input vector as the input of the next processing and further moves the rotary vector to a quadrant including a reference deciding plane. When the moved vector does not exist on the reference deciding plane, prescribed arithmetic is performed and when the moved vector comes to the reference deciding plane, the other arithmetic is performed. Corresponding to these arithmetic results, a timing phase corresponding to the input vector is decided.

Title: Method of rolling synthetic resin band round paper tube
Inventor: YANO MASAYUKI
IPC: B65H19/28
Filed: 1984-02-18
Abstract: PURPOSE:To hold a polypropylene band having commodity value of a paper tube by pressing the leading end onto a paper pipe to which an adhesive agent having a temporary adhesive function is previously applied and temporarily adhering same, and then rolling same round the paper tube. CONSTITUTION:An adhesive agent or a gluing agent is sprayed to a designated position on the surface of an installed paper tube 2 with an air gun and dried about 10 to 15min. Subsequently, when a band of a designated length is wound up round a paper tube 1, a shaft 3 is again turned in 180 deg. arc, so that the paper tube 2 applied with an adhesive agent takes the paper tube 1 position. The leading end of the band is pressed to a designated position 7 of the paper tube with a shock by a hammer the moment the band 8 is cut by a cutter 4. At this time, the adhesive strength of the band to the paper tube, that is, shearing strength is larger than the stress applied upon the adhesive point just after the paper tube starts rotating, so that the band is prevented from being stripped from the paper tube. In order to ensure the adhesion of the band to the paper tube at this time and to easily separate the band from the paper tube at the time of packing, the shearing strength of the adhesive agent may be favorably 0.4 to 2.4kg/cm<2>.

Title: Single-crystal ferrite
Inventor: ONODERA KOICHI
IPC: H01F1/34
Filed: 1987-02-13
Abstract: PURPOSE:To improve the C/N ratio of a single-crystal ferrite by adding a specific weight ratio of silicon oxide to Mn-Zn single-crystal ferrite. CONSTITUTION:0.05-5% silicon oxide is added to Mn-Zn ferrite which contains 45-65 molar % ferric oxide, 20-45 molar % manganese oxide, and 5-30 molar % zinc oxide, the mixture is then mixed, and preburnt according to a normal powder metallurgic method, and produced as single crystal at 1680 deg.C. If the silicon oxide is mixed at a ratio of 0.05% or less, the composition point of high initial permeability is discovered with high saturation magnetic flux density, but its sliding noise similarly increases. If the adding amount exceeds 5.0%, the initial permeability mu excessively decreases. As a result, a head performance C/N is decreased. Thus, the mu tends to decrease, but the C/N can be improved.
